Specification of Letters Patent.

Patented Jan. 2, 1917.

Application filed November 6, 1911. serial No. 658,862.

and resident of Chicago, Cook county, Illinois, have invented a certain new and useful Improvement in Liquid-Metering Tanks, of which the following is a specification.

My invention relates to water tanks or reservoirs for use in connection with concrete mixers, or for use inother places where water is employed for mixing or flushing purposes, and where the conditions are such that the water must be measured off to give the desired quantity each time, whereby the mixing or flushing operation will always be characterized by the right amount ofwater.

The object of my invention is to provide novel and improved means whereby any portion of the water in the tank or reservoir may be measured off to give the desired quantity for mixing or flushing purposes.

It is also an object to provide an improved construction and arrangement whereby a siphon may be easily adjusted to vary the quantity of water to be drawn offfrom the tank or reservoir.

To these and other useful ends, my inven-- tion consists in matters hereinafter set forth and claimed.

In the accompanying drawings, Figure 1 is a side elevation of a tank or reservoir embodying the principles of my invention, showing the same connected with the hopper of a concrete mixer. Fig. 2 is an enlarged sectional view of the valve employed for controlling the admission and withdrawal of water to and from thetank. Fig. 3 is an enlarged partial longitudinal section of the said tank, showing the adjustable siphon mechanism for regulating the withdrawal of the water. Fig. 4 is a transverse section on line l4 in Fig. 3. Fig. 5 is a transverse section on line 55 in Fig. 3.

As thus illustrated, my invention comprises a cylindric tank or reservoir A provided at one end with a depressed or countersunk head a, and at the other end with a convex orbulging head a. Upon the inner surface of the center of the head a the casting B is secured by rivets b, said casting having a stuffing box portion 1) that projects through the head a to receive the threaded cap or nut 6 This casting B has a cylindric chamber with reduced end portions 5 and-b which end portions receive and fit the annular flanges b and b on the horizontal end of the siphon pipe 6 This pipe has the downwardly bent end portion 5 and the lateral openings 5 at its upper end, which openings communicate with the chamber 5 A vertical pipe Z1 enters the bottom of the tank and is screwed into the bottom of the casting 13, whereby the pipes 79 and 6 are always in communication with each other through the medium of the chamber 6 The effect is a siphon of which the pipe 72 is the shorter leg and the pipe 6 the longer leg. A stem 6 is secured to the upper end of the pipe 6 and extends outward through the stuffing box bb a spring 6 and a handle Z2 being applied to the outer end of said stem, said spring serving to hold the pipe in position. With this arrangement, the pipe 6 can be swung around or revolved to any position, as shown in dotted lines in Figs. 3 and 4. When in the position shown in full lines in Fig. 3, nearly the entire contents of the tank can be siphoned ofi'. But with the siphon pipe 6 in a more or less elevated position, a lesser portion of the contents will be drawn off. Thus the horizontal portion of the pipe 6 rotates in the casting B to vary the amount of water drawn off.

Any suitable arrangement can be employed for connecting the tank with the hopper G of a concrete mixer. As shown, the pipe 79 is connected with the top of the three way valve D, which latter has a water supply pipe (Z and a discharge pipe d, which latter leads to the said hopper through a flexible pipe 0, whereby the mixer may tilt back and forth in the usual and well known manner. When the valve D is adjusted as shown in full lines in Fig. 2, then the supply pipe d is cut on and the contents of the tank are drawn off through the pipe cl, to the extent permitted by the adjustment of the siphon. But when the valve is in the position shown in dotted lines in Fig. 2, then the water from the supply pipe d enters the tank, and the pipe cl is out off, whereby the tank may fill.

A siphon discharge tank or reservoir of thischaracter may be employed for various purposes. The adjustment 'for varying quantities is easily accomplished by simple and reliable means. Thus any portion of the contents may be drawn oif at will.

It will be seen that the discharge pipe cl has a siphon head in the tank, this head comprising a fixed pipe I), the swivel bear- 7 ring B and the swiveled pipe 6 as. previously described. 7 is, it will be seen, adjustable without disturbing the offtake cl, and without disturbing the valve D by which the discharge is controlled, and by which the fillingof the tankfis also controlled. The'siphon' head constitutes ooth the inlet and the outlet for the tank,as it is used for filling the tank as well as for discharging the contents therefrom. r

With the foregoing construction, the pipes Z) and 5 and the swivel head B form a siphon, both legs. of which are inside of the tank, the pipe Z) (which leads down- -ward from the swivel head and passes through the bottom of the tank) forming the long leg of the siphon, and the swiveled or swinging pipe 6 forming the short leg of the siphon. that the siphon thus inclosed entirely within the tank is so constructed and arranged.

that the pipe I) swings about the longitudinal axis of the cylindrical and horizontally disposed tank, so thatthe end of this pipe is always the same distance from the' I do not limit myself to the exact construction shown and described.
